Do you use iGoogle? Do you hate the sidebar on the left side that wastes 100 pixels with useless tabs and an advertisement for Google Talk? There's no official way to turn that sidebar off. But if you set your start page to http://www.google.com/ig?gl=all, why there's your iGoogle page without the sidebar. Lovely.
Don't get me wrong, I love iGoogle. I've been using personalized start pages for years and iGoogle is the best. It loads super fast, it's easy to configure, and it has enough useful modules to keep me occupied. Just don't appreciate some product manager deciding to keep features in front of me that I do not want.
